This Project is developing regionally enhanced satellite orbit and clock models to support real-time, centimetre-level positioning services regardless of location.
There are two work packages: one on the regional GPS/GLONASS orbit and clock enhancement system; and one on the regional QZSS/COMPASS orbit analysis platform.
The outcomes will facilitate a wider adoption of nationwide centimetre positioning in agriculture, mining and utilities, construction, maritime, defence and environmental protection applications.
In the sectors of agriculture, mining and construction alone, the benefits can reach the order of several billion dollars per annum due to increased productivity (Allen Consulting, 2008).
A large user group will be the intelligent transportation systems (ITS) sector where precise GNSS and wireless communication techniques are integrated to support vehicle safety systems. Applications of multi-GNSS based precise positioning for nationwide road safety alone can lead to significant social and economic benefits through lives saved and a reduction in losses due to road accidents.
Automated GAMIT and PANDA processing platforms have been setup with Queensland Early Research Node (QERN) virtual servers. The Precise Orbit Determination (POD) processing is capable of generating ultra-rapid (6 hourly) regionally enhanced GPS orbit solution with the recommended 120 stations configurations.
Through the collaboration with Wuhan University, the regionally enhanced clock solution is also provided by the PANDA processing. The real-time PANDA orbit and clock products are now available with 50 regional CORS stations configuration.
Prof Yanming Feng and Matt Higgins presented at the International Symposium on GPS and GNSS on 31 October - 2 November in Xi’an China. Matt was invited to give a keynote speech.
